Clouds

A cloud is a visible body of very fine water droplets or ice particles suspended in the atmosphere at altitudes up to several miles above sea level. They are generally produced by the condensation of water vapor. Other clouds, less commonly seen, are composed of smokes or dusts.

Why is central air conditioner not giving cold air?

You need to call an air conditioning company. Sounds like either it needs to be recharged or the compressor has died.

Do clouds taste good?

Clouds do not have a very strong taste. They are made up mostly of water vapor and dust, so they have a flat, mineral flavor, were one to taste a cloud.

What is the usual shape of a tornado?

Tornadoes come in different shapes, and the shape changes during the life of the tornado. Some tornadoes are like thin tubes or ropes, some look like large wedges. If it is wrapped in rain, or there isn't enough light, it can be hard to see a tornado. Sometimes clouds may look like a tornado but aren't, so looking for other clues like rotation is important.

What is wrong when your central air conditioner is not blowing air as strongly as it usually does?

If the air flow is low, a primary filter or return register filters could be clogged, or your blower unit could have a faulty fan. If the air is warm then your condenser unit may need to be recharged/checked for leaks.

The Air conditioner on your 2001 Taurus blows cold air for a short time then all you get is hot air How do you check to see if you need to recharge it?

Purchase and inexpensive recharging kit from the parts store... add coolant while the vehicle is running and after you recharge it turn the motor off and you night be able to hear a leak... if not then start with a recharge kit that has the florescent dye in it and that might help finding the leak... more than likely there is a leak...

What is the definition of low pressure?

Normally pressure lower than 1018mb, Relative to sea level. that is about 30.00 in Hg

1990 Toyota corolla rr power window went down - will not come back up using frontrear buttons Toyota service said they could prop it up with a 2x4 but that it would problably come smashing down?

the window motor is bad. order a motor . then have it replaced. easy to do your self. former Toyota tech.I would try replacing the switch that controls the problem window first. I had the same problem with the front passenger window of a 1999 Corolla. I thought it was the motor at first but when i put the switch from the rear window on it, it came up just fine. I don't know why, but it also effects the driver's control panel.

Does your HVAC system need servicing if the low side pressure is 90 and the high side is 150 and the outside temperature is 94 and the inside temperature is 90?

Yes. Was the compressor running?

Answer Depends on the refrigerant, but for residential systems they use either R22 or R410A, and those pressures are not right for either system. If the compressor was running, sounds to me like you have bad valves in the compressor and probably need a new compressor (or a new system)

Is a humidity control such as a thermidistat necessary with a 13 SEER air conditioner in an 1800 square foot 1 story home in Florida?

The first question you need to answer this is are you occupying the home year round? If you are NO. If you are a snowbird, then you should have a Humidistat installed to keep the moisture level down as to not grow mold. If you are there year round, then normal use of your A/C will keep the humidity at acceptable levels.

What's wrong with a central air conditioner unit when it keeps dimming the lights in the house on and off and blows warm air out of the vents?

The lights dimming are a sign that it's drawing too much electricity in relation to the amount of electricity that's being supplied to your house overall.

The compressor trying to start is drawing too much current. It could be that the compressor is locked up. It could also have a bad start or run capacitor.

Why does temp gauge go up when car is sitting with ac on but doesnt go up when ac is off?

Freon in the AC system heats up very hot before it is sent through the condenser. The condenser is like a radiator, and is located right in front of the radiator of your car. As air passes through the condenser & the radiator , the hotter the condenser, the hotter the radiator will be. correct answer the temp goes up when using a/c as the motor is running at a higher speed to drive th a/c , therefore when idling the fan is not pulling anuff air over engine. a thrmatic fan will help with this

Why would the central ac blow cold air for about 30 minutes then start blowing hot air but the unit isn't frozen and is full of refrigerant?

It could be that the unit is overcharged and the compressor is shutting down on overload. Check to see if the compressor is running when the hot air starts blowing.

Is there some kind of agreement letter with a collector that would allow the removal of a collection if paid?

There is the kind of letter that you write insisting on this condition prior to paying a collection account. There is also the collection agencys' written agreement stating this. There is no standard form letter.

If using muriatic acid do the fumes rise or stay near the ground without air movement?

== == While the fumes of muriatic acid (hydrochloric acid - HCl) are slightly heavier than air, the oxidation reaction is highly exothermic. The acid fumes will react with things in air, and generate heat. The heat generated causes gases to rise, so muriatic acid co-oxidant gases will fill the surrounding space. Fumes also mix quickly without heat due to diffusion. A link can be found below to the Wikipedia post on hydrochloric acid. If you are using concentrated acid in still dry air the fumes will not be too bad however you should stil take care. However if you use the stuf in cool conditions especialy in the morning with mist in the air the area around you will soon become a toxic cloud of acid vapor.

If you have a multi story building and with 40 psi water pressure coming in at what height do you put a booster pump?

This depends on what your target pressure is.

If the height of the pipe is H in feet, the pressure at the bottom of the pipe from the column of water is 0.036127292 * H * 12 where 0.036127292 is the density of water in lbs/in^3. Thus, if your initial water pressure is I, the pressure at H feet will be I - 0.036127292 * H * 12

So you will have

Height | Pressure

+---------

0 ft | 40 psi

10 ft | 35 psi

20 ft | 31 psi

30 ft | 27 psi

40 ft | 23 psi

50 ft | 18 psi

60 ft | 14 psi

70 ft | 10 psi

80 ft | 5 psi

90 ft | 1 psi

100 ft | 0 psi

One will be required above 90 ft. You'll probably want one above 40 ft.

Derivations: eq means equals. This wiki eats equals signs.

D eq diameter of the pipe in inches, H eqheight in feet

Water weight (W)(lbs) eq V * 0.036127292 eq pi * R ^ 2 * H * 12 * 0.036127292

Pressure (P)(psi) eq W / A eq V * 0.036127292 eq pi * R ^ 2 * H * 12 * 0.036127292 / pi * R ^ 2 eq H * 12 * 0.036127292

Why would a 1995 GMC 350 make a tapping sound when cold that gets louder when warm?

If it is a Tapping sound it is normally a lifter. Could also be a cam, pushrod, and or a rocker arm. Tapping is normally upper motor. If it is a knocking noise it is normally in the lower motor. If the noise gets louder when warm most likely a lifter is going bad. As the oil heats it thins slightly causing more oil to bypass inside the lifter which it is not supposed to do

How cold should the air be that comes out of the house's ducts with the air conditioner on?

The air coming out your vent should be about 16 to 20 degrees cooler than the air being sucked into your unit through the return.

More Information:

I usually set the unit to where it blows out at about 55 to 60 degrees. Any cooler than this means the fan is not blowing fast enough and any warmer, the fan is blowing too fast. This will work on all units if sized right.

If the unit was sized properly the supply air temp should be 18 to 20 deg. F. colder then the return air. [ return air temp should be taken at the indoor air handler because if your duct work has leaks it will pull hot air from your attic or ceiling giving you a false reading.] Also a properly sized unit will make a temperature difference of 20 deg. F. out side to inside air. [ 90 deg. outside 70 deg. inside. ] I have 20 years field .

Rule of thumb is 20 degree split across evap coil. (between return air and supply air )

Was it a mistake to install air conditioner returns directly to outside air in high humidity Washington DC?

Yes. You will never get the type of performace from the unit you expect. The life of the unit is seriously degraded. You will have high humidity in the house, because the unit can't dry out the wet air as it could from an interior return. numerous bad issues here.
